Answer:
Explanation:
solar cell - converts sunlight into electricity
geothermal energy - heat produced within the Earth
wave energy - turns turbines along coastlines
hydroelectricity - water falling through dams turns turbines, generates electricity
A. an ion
The atom gains a net electrical charge if the number of protons and electrons are not equal which makes it an ion.

Answer:
independent variable -- different batteries
dependent variable -- the time that clock stop
Explanation:
In an experiment or a research study, there are two type of variables that can affect the result of the experiment or the conclusion. They are independent variable and the dependent variable.
An independent variable may be defined as that variable in an experiment which can be changed or can be controlled in the scientific experiment in order to test the effect on the dependent variable. It cannot be changed by other variables.
On the other hand, dependent variable are those are those which can be altered or change that can affect the experiment.
In the context, Emily uses the different types of the batteries as an independent variable and the time where the clock stopped in the dependent variable in her research.
protons and neutrons are in the nucleus electrons surround the atom and i have no idea what positrons are i just know they arent in an atom so your answer is B and C
